On March 27, 2017, the FCC adopted final rules for the USA 630-meter band, detailed in Report and Order FCC 17-33, which required PLC coordination with the Utilities Telecom Council before amateur operations could commence. This resource documents the WD2XSH experimental group's activities, including authorized stations, band plans, and frequency assignments within the 465-515 KHz range, with many stations operating between 495-499 KHz and 501-510 KHz. The site also highlights the WRC-12 decision on February 14, 2012, which granted a new **7-kilohertz-wide** secondary allocation between _472-479 kHz_ for the Amateur Radio Service worldwide. The group's efforts included operating with a maximum ERP of **20 Watts** across 45 stations in the continental USA, Alaska, and Hawaii, using emission modes such as CW, PSK-31, FSK-31, and MSK-31. The site provides links to download FCC 17-33 in PDF and DOCx formats, and offers a station location map, a list of stations by callsign and frequency, and an archive of news updates. Reception reports for any 600-meter station are encouraged to help the amateur radio community understand propagation and repeatability on this challenging band.

Demonstrates the practical application of APRS (Automatic Packet Reporting System) through the lens of HB9PVI's activities in Switzerland. It covers the system's core function of reporting geographical positions and telemetry data from various objects, including mobile stations, aircraft, and the ISS, distributed via packet radio and internet gateways. The resource highlights the routing paradigm shift introduced in April 2005, specifically the recommendation to use _WIDE1-1_ instead of RELAY and WIDE for digipeating to reduce duplicate packets. The page presents real-time maps displaying the positions of amateur radio stations in Switzerland and around Bern, updated every few minutes. It details specific callsigns like _HB9BA-2_ (HB9PVI's home QTH), _HB9BA-8_ (a weather station), and _HB9BA-4_ (a WIDE digipeater on Weissenstein mountain), providing context for their roles within the local APRS network. Links to track HB9PVI's mobile operations (_HB9PVI-9_) and handheld devices (_HB9PVI-15_, _HB9PVI-7_) are also provided. Furthermore, the resource curates a list of APRS software options for various operating systems, including _JavAPRS_ for Europe, _UI-view_, and _X-Astir_ for Linux, alongside digipeater/IGATE software like _DiXPRS_. It also offers downloadable APRS information, including a PDF article by HB9PVI and HE9ZGN, and a PowerPoint presentation in German, making it a repository of practical and historical APRS data.

The Waterway Net, sponsored by the Waterway Radio and Cruising Club, is dedicated to enhancing amateur radio communications for recreational boaters. Meeting daily at 0745 ET on 7.268 MHz LSB, the net focuses on safety and weather updates, providing a vital link for live-aboards and cruising boats to stay connected with families and friends. Position Reports and Float Plans are essential components that ensure safety for offshore passage makers. Established in the early sixties, the Waterway Net is one of the longest-running nets in amateur radio history. Open to all amateur radio operators with a General class license or higher, it encourages participation without requiring WRCC membership. Newcomers are advised to listen initially to understand net procedures before checking in. In emergencies, FCC regulations allow anyone, licensed or not, to use any frequency to call for help, with the 20-meter frequency of 14.300 MHz available for emergency assistance approximately eighteen hours a day.

The widget displays UTC time, current HF propagation conditions, local weather, and thunderstorm risk. It also integrates radio-related links and offers advanced PRO functions, such as a DX map, HF noise radar, IBP beacon synchronization, contest heatmap, aurora radar, and a rare DX radar. The software is available for Windows 10/11 and Linux, with a macOS version planned for future release, and supports both French and English interfaces. Author HB9HBY highlights the widget's simple installation process and automatic update capabilities, which can be silent for minor fixes or include notifications for significant changes. The free version provides core functionalities, while a 15-day free trial unlocks the PRO features. A lifetime PRO license is available for a one-time payment of CHF 10, activating advanced tools that help operators make quicker decisions at the station by correlating propagation, UTC, DX activity, and local conditions, though results remain indicative and require confirmation via listening or tools like _RBN_ or _PSKReporter_.

Operating a web-based DX cluster, this resource presents real-time amateur radio DX spots, facilitating contact logging and propagation analysis. It leverages the Spiderweb platform, offering users the ability to filter DX spots based on various criteria, including inclusion and exclusion rules. The interface integrates directly with QRZ.com for immediate callsign lookups, displaying flag icons for geographical context, and provides charts and statistics derived from spot data. Further enhancing its utility for DXers and contesters, the cluster includes direct links to MUF (Maximum Usable Frequency) maps and HamQSL solar condition reports. These external data sources provide critical propagation insights, assisting operators in making informed decisions about band selection and operating times. The service also offers Telnet access at dxc.sv5fri.eu:7300 for those preferring a command-line interface.

The N7YG Digital Engine, functions as a streamlined digital modem, supporting **PSK**, **RTTY**, and **MFSK** modes. It eliminates many ancillary logging and awards features found in other software, focusing instead on providing a dedicated digital interface. The software is specifically engineered to complement the N3FJP logging suite, offering a simple digital modem with a floating waterfall display that can coexist on the same screen as the logger. The application includes support for PSK Reporter, EXTFSK, TinyFSK, and K1EL Winkey FSK, enhancing its utility for various digital operations. Key features comprise a separate waterfall window, a main GUI with operational controls, receive and transmit display areas, and 10 Macro Buttons across 10 user-definable macro banks, totaling 100 macros for general and contesting use. Configuration options include sound card selection, digital gain (0-32767), AFC Level (0-100), AFC Width (in Hz), and COM Port TX keying for VOX/SignaLink or direct port control. Input and Output Mixer buttons provide direct access to OS audio mixer controls for precise level adjustments. The software is digitally signed with a security certificate, aiming to prevent conflicts with antivirus programs.

Version 0.7 of Open Tuner, released on April 27, 2023, marked a significant milestone by introducing proof-of-concept dual tuner functionality for the BATC Minitiouner. This C# client, inspired by Heather Lomond's _Longmynd_ project, aims to leverage both tuners and demodulators within the NIM module, a capability crucial for advanced Digital Amateur Television (DATV) operations on QO-100 and terrestrial links. My own experience with DATV often involves juggling multiple receive paths, so a unified client like this simplifies the workflow considerably. Further enhancing its utility, version 0.9 (February 11, 2024) integrated support for the Raspberry Pico, utilizing Colin (G4EML)'s _PicoTuner_ firmware. This offers a more accessible and cost-effective alternative to the traditional FTDI module, streamlining dual tuner setups with a single USB cable. The project's evolution reflects a practical approach to overcoming hardware availability challenges. The software is developed using Visual Studio 2019/2022 and .NET Framework 4.7.2, requiring specific Nuget packages like VLC/Websocket and an ffmpeg folder for full operation. It's an active, community-driven effort, with the source code openly available on GitHub for contributions and bug reporting, embodying the collaborative spirit of amateur radio development.
